Access ginjector

[Tushar Bhasme]

Is there a way to access the ginjector created by gwtp? I need to create a standalone widget but it needs access to EventBus and DispatchAsync implementations which I wanted to get through the ginjector. Since I want it to be standalone, I do not want to inject anything. I actually want to create this class using Builder pattern and I want it to resolve the core dependency by itself.

Thanks,
Tushar

A working solution but a bit ugly : you create a "factory" class and declare it as eagerSingleton in your gin module.

public final MyFactory {

  private static Provider<EventBus> eventBusProvider;

  MyFactory(){}

  public static EventBus getEventBus(){
    return eventBusProvider.get();
  }

  @Inject
  void setEventBus(Provider<EventBus> eventBusProvider) {
    MyFactory.eventBusProvider = eventBusProvider;
  }
 
}

You might also want to consider using requestStaticInjection(YourWidget.class) inside your Gin module

Seems static injection would give me same result as the Factory suggested by Nicolas, just in a little cleaner way.

So to inject at instance level, I would have to inject a static Provider?

The EventBus is bound as a singleton, so I'm not sure there's a benefit in injecting a provider instead of injecting the EventBus itself
